The Challenge

The high energy expenditure, constituting the primary operational cost, was a major concern for the company. They aimed to find alternative energy solutions to reduce these costs effectively.

Our Solution

PRODENSA Energy conducted a thorough analysis of the company’s energy demand throughout the year, considering the cost of energy at different times of the day and year. We also evaluated the available area for PV generation. Based on this analysis, PRODENSA proposed a combined system:

  • PV Generation: A system with a 600 kWp capacity, designed to cover 19% of the company’s energy needs. This system includes 1090 panels spread over 4200 sqm, generating approximately 996 MWh annually.
  • Tesla BESS System: A 1500 kWh capacity battery energy storage system (BESS).

The PV and BESS systems are part of a Power Purchase Agreement (PPA) where the energy generated is sold at a lower cost than the national grid. The BESS system allows for peak shaving (using batteries to reduce demand peaks) and load shifting (using batteries to store energy during low‑cost periods and use it during high‑cost periods).

Financial Plan

PRODENSA offered the entire system with zero initial investment required from the customer. The project financing is brought by PRODENSA, leveraging the savings from reduced energy costs, amounting to at least 25%. The commercial proposal has a term of 15 years, including all operational expenses for the PV system in the rates, plus a tax benefit for using clean energy.

At the end of the term, all assets are transferred to the customer. The accumulated savings for the customer over 25 years are projected to be 6,5 million EUR, with no initial investment required from their side.

  • Cost Reduction Significant reduction in energy costs through PV generation and efficient energy storage and management.
  • Zero Initial Investment The project is fully financed through PRODENSA, reducing the financial burden on the customer.
Key Benefits
  • Sustainability Utilization of clean energy sources provides tax benefits and aligns with sustainable practices.
  • Long‑term Savings rojected savings of 6,5 million EUR over 25 years.

Outcome

This business case demonstrates PRODENSA’s ability to reduce operational costs and provide significant financial and environmental benefits to a company with a huge energy consumption without any initial investment.
